New retrieval method tackles noisy user profiles in conversational AI

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced Personalized Conversational Dense Retrieval (PCDR), a novel method for improving conversational information access systems. PCDR addresses the challenge of noisy user profiles by jointly projecting conversation history and user profiles into an embedding space optimized for retrieval. This approach aims to better identify user information beneficial for retrieval, unlike previous methods that rely on LLMs for query expansion. AI

IMPACT This method could improve the personalization and accuracy of AI assistants in complex information retrieval tasks.

    RALI@iKAT 2026: Retrieval-aware User Profile Denoising via Personalized Conversational Dense Retrieval

    Modern conversational information access systems continuously extract user information from conversations to build user profiles for personalized retrieval. As user profiles accumulate over time, they inevitably become noisy, making effective user profile denoising a fundamental …
